Welcome to the Seattle waterfront construction information site!

Seattle's Central Waterfront is going to be a busy place over the next several years, with multiple construction projects underway. To make it easy for you to stay up to date on what's going on and what's ahead, we've compiled project information all in one place. This site provides general information about current and future public projects. For additional project details, visit the project websites, which can be found in the “Contact Us” page.

2Colman Dock (open during construction)

Washington State Ferries is replacing the aging and seismically vulnerable parts of Colman Dock in Seattle in order to maintain its critical role as a regional transportation hub. Project construction began in 2017 and will continue through early 2023. The terminal will remain open throughout construction. The contractor will complete most work from barges on the water, however, construction work zones on the dock will limit vehicle holding capacity. Ferry service will maintain the same number of daily sailings as the current schedule.

What’s happening now?

This fall, work will take place on both the south and north sides of Colman Dock.

5Removing the Alaskan Way Viaduct

Anticipated activities

Removing the Alaskan Way Viaduct between Railroad Way S and the Battery Street Tunnel.

The work began in early February 2019 and will take approximately six months.

Construction details

Crews will remove the viaduct in sections, to reduce the work duration at any given location.

Work will occur at multiple locations at once. At most locations, crews will remove a frame of the viaduct within 30 days. This 30 day period includes time for staging and prepping the work area, demolishing the viaduct, and restoring the work site.

Visit the program website for more details about work methods and schedule.

7Marine Habitat Improvements

Construction on marine habitat enhancements just south of Colman Dock and west of Alaskan Way began in late October (see map below). The work will create an intertidal area to improve the function of the natural ecosystem along our urban shoreline. The work will have no impact to parking, pedestrians or vehicles. This area will remain closed to the public until 2023 to allow enough time for plant establishment.

Status updates

March 2019

Viaduct demolition

The contractor will close lanes only in immediate proximity to active construction.

One lane of Alaskan Way will be open in each direction adjacent to active construction. Elsewhere, two lanes will be open in each direction.

There will be no fixed bicycle/pedestrian detours during construction, as the work zone will be frequently moving up and down the structure.

Colman Dock

Colman Dock is open during construction

The passenger-only ferry facility has been temporarily relocated to the north side of Colman Dock. Passengers can enter from Alaskan Way between Madison and Marion streets

All drive-on customers, including cars, trucks, vanpools and motorcycles enter from S. Jackson St. Passenger pickup and drop-off access will remain in front of the terminal building on Alaskan Way. There are no changes to access for people walking or biking onto the ferry.

Pier 62 Rebuild

The west side trail will remain closed for the winter between Lenora and Pike streets and will reopen by Memorial Day.

Road restoration work on Alaskan Way near Pike Street has been completed. The four lanes of Alaskan Way, the Pike Street crosswalk and the Pike Place Market Garage driveway are now open.
